Specification of Letters Patent. I Patentd June 20, 1916.

Application filed i'arch 15, 1915. Serial No. 14,417.

T 0 all whom z't may cono'rn:

Be it known that I, STANLEY RAMS- no'rHAM, a subject of His Majesty the King of England, residing at Streatham Hill, in the county of London, Kingdom of England, have invented certain new and useful Improvements in or Relating to Vehicle- Wheels, of which the following is a specification.

'This inv'ention has for its object the construction of metal wheels so as to enable solid elastic tires of the band type to be Secured thereto in a detachablc .manner so that such tres may be fitted or *removed without the necessity for a press.

The invention is conce'rned essentially with wheels of the cast or welded-up type, wherein the hub, the spokes, and'the rim, are integrally connected together.

With the above object in View, thepresent invention consists 'in forming a metal wheel with a flat rim having a continuous circumferential division, that is to say, the rim conprises two rings side by side. Each rin part is connected to'the hub by a set of spokes, the two sets of spokes being oppostely inclined to the vertical plane ofthe wheel.

The next, and essential 'feature of this invention consists in the provision of means at or in proximity to the rim parts for effecting transverse flor axial ,adjustment' thereof, with a consequent alteration of the inclination of the spokes. This variation in the inclination of the spokes is' made use of to secure or release a band tire or tires fitted over the rim.

Referring to the accompanying drawings in which the principle of the invention 'is illustratedz-Figure 1 is a part'vertical section of 'a metal wheel showing one form of the invention; Figs. 2, 3, 4, 5, 7, 8, 9, show various modified methodsmf carrying-the invention into effects; Fig. 3 is a detail of the device shown in Fig. 3; and Fig. 6 is a side elevation of a wheel-embodying the ar- I rangenents shown in Figs. 7, 8, and 9.]

Referring to Fig. 1 s representsspokes, and t, a hub of ordinary construction, the spokes on one side ofthe wheel inclining toward those' on theother in the direction ot' the rim c. The rim is divided at 0 th&

rim parts being provided at suitable inter vals around the wheel with brackets (l adapted to receive the thrust of right and left threaded bolts e operated by correj-outer ends of the spokes. 'simple method of e'tfecting this operation v sponding nuts f. The tire a With the metal base band b is the ordinary 'band ti-re of' commerce, the parts being so construcbed that when the division 6 is closedor nearly closed, the band b may be slipped over the rim ,0. If now the'spokes are spread by means of the nuts f, the radial throw" of the outer ends of the spokes will be increased with the result that the rim parts c are caused 'to grip tightly the inside of the band b. i v I Referring to Fig. 2,',the rim parts are provided with spaced brackets 'br-k those (h) on one', preferably'the outer side of the wheel being tapped tojreceive thrust bolts g adapted to bear against the opposite brackets h whereby thenecessary separation of the spokes is efl'ected.

nected to the opposite side of the hub. In

such cases, 'eX'pansion of' the rim elementsdue to the increased radial throw? of the spokes-is efiected by drawing together the A suitable and comprises bolts `m passed 'loosely through brackets n on one -side of 'the wheel, and screwing into brackets n on the opposite side'of the wheel.

Referring'to Fig.. 5 in this modification a split ring p of wedge section bears against taper surfaces 0 on rings o (or brackets)' carried by the rim parts a. suitable screw, toggle, or equivalent mechanical devices may be' emplo'yed to expand the ring p whereby the necessary separation of the spokes is efl'ected.

'Beferring to Figs. `6 to' 9, a series of wedged segmente p engage taper surfaces c on therim parts cand taper shoulders ,s onthe outer endsof the spokes.

The segments are forced outward by means of bolts or set screws p sc'ewing into' brackets 7)* cu rried by one of the rim parts as clearly shown in Figs. 6 'and 8. Figs. 6, 7 and& show also a means of separatng the spokes consisting of bolts 8 'screwing into bosses .2 formed on one set of spokes and hearing against suitably formed bosses 8 on the opposite spokes. As shown in Fig. 9 the bolts 8 may be formed With taper ends s* adapted to bear under the ends of the wedge segnents 1 to assist in forcing the latter outward.

If desired I may enhody a divided hub in a 'wheel ';onstructed in accordance with ny invention 't'or exanph in the nanner shown in Fig. T wherein tlieavheel is divided at the hnl inaddition to the division c' at the rim. One set of spokes is carried on the huh part u; which has a reduced part a on which is adapted to slide the hub part 3 cartvin the other set of spokes. By drawing together the huI-parts hy means of the holts '3 the ontward expansion ot the spoke and rn elements may be asssted or augnented;

Obvionsly other devices may be employcd at the h'nh in the cases where this is divided, such, tor example., as are described ahove in connection with the rim or oiter ends ot the spokes.

The hraekets, lngs, or the like, may he l'o'ned integral with the rim, spokes, or hub, or may he secnred thereto hy welding,

hrazing, ri\`etin;', or in other co'venient nanner.

In desgnng thevwheels, I p'e'terahly arrange that the stram m the spokes s set up during or to faeilitate assemhlage ot the tire'or tires so that the wheel parts assume to a great or less degree their 'normal condition when the tire is finally gripped;

`What I claim and desire to secure hy Letters Patent of the United States is:-

1. A metal rim comprising a hub, a removahle rini, a divided rim, spokes carried hy the said hub and portions of the divided rim and so arranged as to normally hold the divided portions ot' the rim together, and means for n'oving portionsot said divided rim outwardly from the hub and in contact With the removahle rim and novin'g' 'said divided rim portions a'way tron each other.

2. A metal wheel conprising a hnh, a rim composed ot' a pln'ality of sections, s'pokes carried by the hub and the sections ot' the rim and so arranged as to normally hold the said sections of the rim together, and means- -for moving portions of the sections of the rim outwardly from the hnh'and away -fron each other for the purpose described.

3. A metal wheel comprising a'hub, a circumferentially divided rim, spokes carried' hy the hub and the divided sections of the rin, the said spokes' so arranged to normally hold the said sections of the rim together, 'and means for noving portions of the said sectionsofthe ri'n outwardly from the hub and away from each other for the mrpose described.

t. A metal wheel comprising a, hub, a circnnferentially divided rim, spokes carried by the hub and the divided sections of the rim, the said spokes so arranged as to normally hold the said sections of the rim together, and adjnstahle means for moving portion& ot' and for holding the said sections of the rim outwardly from the hub and away from each other for the purpose described? i\ metal wheel comprising a huh a. circnterentially divided rim, sphkes da ried by the hub and sections of the rini-Kthe said' spokes inclined inwardly whereby,the sec: tions ot the rim are normally held together, and means foroving portions of and for` holding the said sections of the rim outwardly :t''om the hnL and away from each other l'or the purpose described.

i. i\ metal wheel comprising a hub, a cirenmferentially divided rim, and two sets of oppositely inclined spokes connecting the said hnh to the said divided rim, and means for positively etl'ecting transverse or axial adjustment ot' portions of the said rim parts and noving said parts outwardly from said hub 'or the purpose described.
